METAL LAST.

SPECIFICATION forming part of Letters Patent No. 240,601, dated April 26, 1881.

Application filed March 7, 1881. (No model.)

To all 'whom it may concern Beit known that I, SAMUEL MAWHINNEY, of Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Metal Lasts forBoot and Shoe Makers 5 and Ideclare thefollowing to beadescription of my said invention, sufficiently full, clear, and exact to enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Iron lasts have heretofore been made with a projecting stem or shank formed upon the top of the last or upon the instep-block, said stem having a rectangular end adapted to fit into a socketed standard for supporting the last in workin g position. These kinds of lasts are somewhat clumsy and heavy and inconvenient to handle, owing to the projecting stem. Lasts have also been made and used in which a straight or slightly-tapered socket was formed for fitting onto the end of a supporting-standard. In this form the socket becomes worn or enlarged, so that the last does not stand rmly on the standard when hammered upon and occasions considerable an# noyance by its Tooseness.

My present invention relates to improvements in the construction of metal lasts with a view to the obviat-ion of the above objections, the object thereof being to make the last light and convenient in form, to adapt the last to be readily adjusted upon and secured to a supporting-jack, and to furnish facilities for the connection and secure attachment of the jackj I attain these objects bya last' ing devices. constructed in the manner shown and described.

The drawings illustratemy invention in several modifications adapted to different styles of jack or support mechanism.

Figure lis a side view of my improved metal last. Fig. 2 is a plan or top view of the same. Figs. 3, 4, 5, and 6 show sectional views of the same, illustrating some modifications of construction embraced within the scope of my invention.

A denotes the body of the last and B the instep-block. The rear part of the body A is made low, with a straight top, at a, or surface substantially as of such form as will fit the supporting-jack and rest squarely thereon. Said body A is provided with a cavity or recess, 0,'the same being undercut, dovetailed, or internally enlarged, so that the inner portion, C', of said recess is of greater dimension than the top opening, G2, thus giving at the front, rear, or sides of the cavity one or more lugs, bevels, or offsets, D, which will afford a gripe or lock for the tongue or bar of the jacking mechanism employed for drawing the last against the supporter-standard and retaining it firmly in position thereon.

These metal lasts are designed to be used with a jack or supporter operating in principle substantially as that described in my application of even date herewith. t

'Ihe top of the last A may be provided with a rib, stud, or projection, E, as shown, to serve as a guide, when placing the last in position, by fitting into a corresponding depression, or vice versa, on the supporter, and to assist in retaining the last in place laterally.

Fig. l shows a form of recess, 0, and lugs D, adapted to be used with ajack-tongue made in the form of a double latch; Fig. 3 for a single latch. Fig. 4 is adapted for a single or double hooked tongue. Fig. 5 is a dovetail adapted for use with a jack-tongue formed and acting in the manner of a 'lewis-iron, while Fig. 6 is adapted for a T-shaped tongue, the slot Cz being long and narrow and requiring a quarter-turn to give the lock.

I do not desire to confine myself to the exact form of cavity anymodiication thereof adapted to perform the essential functions of a jack attachment within the body of the last may be employed without departure from the nature of my invention.

By constructing metal lasts iu the manner set forth I avoid objectionable projections, make the lasts light and convenient to handle, provide a means for secure attachment to the supporter, and reduce the cost of their manufacture.

What I claim as of my invention, and desire to secure by Letters Patent, is-
